Connected Papers is not a citation tree, but rather a similarity graph. It uses the concepts of co-citation and bibliographic coupling to measure the similarity between papers based on their citations and references. This means that even papers that do not directly cite each other can be strongly connected and very closely positioned in the graph. You can also use Connected Papers to find important prior and derivative works, create your bibliography, and discover recent state-of-the-art papers.
Connected Papers supports hundreds of millions of papers from all fields of science, thanks to the Semantic Scholar database. It is a unique and visual tool that can help you with your literature search workflow. You can try it for free at https://www.connectedpapers.com/ or subscribe for $3 per month (billed annually) to get access to more features and support the project. You can also apply for a scholarship program if you truly can not afford a subscription.
Connected Papers started as a weekend side project between friends who have been working with academic papers for years and felt a great need for better tools for science and research. They decided to release it to the public for the benefit of the scientific community. You can learn more about their story and contact them at https://www.connectedpapers.com/about.
